Improvement in take-ups for narrow-ware looms



UNITED STATES PATENT OEEIcE,

MARTIN WOLF, OF NEW YORK, N. Y.

IMPROVEMENT IN TAKE-UPS FOR NARROW-WARE LOOMS.

Specification forming part of Letters Patent No. 58,708, dated October9, 1866.

To all whom it may concern: f

Be it known that I, MARTIN WoLE, of New York, in the county and State ofNew York, have invented a new and useful Improvement in Looms 5 and I dohereby declare that the following is a full, clear, and exactdescription of the construction and operation ot1 the same, referencebeinghad to the annexed drawings, making a part ot' this specitication,in which- Figure I is a perpendicular section, Fig. II a front view, andFig. III a top view, of my improvement.

My improvement relates, particularly, to looms for weaving ribbons,bands, or trimmings, and is for the purpose of regulating the exactamount ofthe finished work to be taken up, dependent on the thicknessofthe woot or weft.

In looms as at present constructed the band or woven article, afterpassing over a roller, A, near the breast'beam of the loom, passesdirectly to the roller B, operated by suitable gearing, so as to take upthe exact amount inished by each throw ot' the shuttle.

Any irregularity in the thickness ot' the woot' or wet't, particularlywhen the article is woven very tight, will, by the arrangement as atpresent in use, be very perceptible, as the amount taken up by theroller B is, after once regulated, always the saine. To regulate thisdifficulty resulting from the irregularity ot' the woot' or weft formsthe nature ot' my improvement, which consists ot' a sliding block, O,arranged between two frames, D D, fastened together by the bars E E, andattached to any convenient part ot' the frame of the loom. Near theupper end of this sliding block O a roller, F, turning freely on itscenters, is arranged, and a roller, G, likewise turning freely around,is arranged near the upper ends ofthe frames D D.

To the lower part of the block C a pulley, I'I, is attached, and on thelower part of the frames D D a pulley or roller, K, is arranged.

The ribbon, band, or other material, after having passed over the rollerA, is passed below the roller F in the sliding block O, then over theroller G in the fixed frames D D, and then to the takenp roller B.

A cord, L, is fastened to the bottom ot' the machine, or to the iioor ofthe room, passes then over the pulley H in the lower part of the slidingblock O, around the stationary roller or pulley K, then over a pulley,l?, tiXed to any convenient part ot' the loom, and has a weight, W,attached to its end.

Instead ot attaching the weight W to the end ot' the cord L, andoperating through said cord upon the sliding block O, said weightmay beattached directly to the bottom of the sliding block O. By thisarrangement of a mova ble roller between the rollerA and roller B anyirregularity in the thickness ofthe woot' or wett will be easilyregulated without any further attention ot' the operator, and greaterregularity and evenness in the texture ot' the material woven will beobtained.

By regulating the weight at the end of the cord L, or at the bottom ofthe sliding block C, the tightness otq the texture woven may be easilyregulated without changing the motion ot' the roller B.

What I claim as my invention, and desire to secure by Letters Patent,is-

The arrangement ot' a movable roller, F, attached to a sliding block, O,and operated or acted upon by a weight, in combination with a stationaryroller, Gr, when applied to the Woven material at anyplace between thebreastbeam roller A and the take-up roller B, in the manner and for thepurpose substantially as set forth and described.

MARTIN WOLF.
